Consumers are relying on e-commerce platforms as reliable shopping venues with 9 out of 10 consumers having made an online purchase just last year. There are fewer consumers that have not had an online shopping experience, with 7% have never shopped online, compared to 22% just four years ago in 2009. Today's consumers are more sophisticated online and vendor solutions need to continue to evolve. Javelin's study evaluates e-commerce processors' platforms in five categories: core back-end processing functions, domestic payments, international payment processing, fraud and security features, and mobile capabilities.

"Retailers such as Amazon and Walmart are setting the bar high for online merchants," said Nick Holland, senior analyst, payments at Javelin Strategy & Research. "E-commerce shoppers want convenience, they want speed, and they want security, and it is up to e-commerce platform vendors to provide merchants the tools to allow these wishes to be fulfilled in order for e-retailers to stay competitive. Yet, the study found that ecommerce platforms were slow to adopt current generation features such as responsive design and few platforms were designed to support digital wallets such as Google Wallet, Visa's V.me and MasterCard's MasterPass."
